what do others add to their baked bread ?

Me and my DD have mastered bread baked in the Oven since she made Bread at school last week. It's been so successful we made it three times each time with cheese inside and on top. We platted the bread it's all very Masterchef right now. What else would be interesting to add to the bread other than cheese any ideas ? I could only think of olives but I don't think we'd like that ?
